Personally, I would love to see this game taken into the atmosphere of a planet(changing a few rules) or land based battles. I am not talking down to the individual, but down to the speeder level would be nifty. I could imagine an AT-AT or AT-ST and speeders to recreate hoth using the current engine (with a few rule changes of course). That way a campaign could consist of an epic battle in space around a planet followed by a land based battle.
*edit* I realize that this is a bit off topic as I am unsure which other games these rules would come from, however, they are mechanics changes to the game so figured I would post.
